Below is the list of asteroid close approaches to Earth in 2017.

Timeline of known close approaches less than one lunar distance from Earth in 2017

A list of known near-Earth asteroid close approaches less than 1 lunar distance ({{convert|0.0025696|AU|km mi|abbr=on}}) from Earth in 2017, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS).{{cite web |url=https://cneos.jpl.nasa.gov/ca/ |title=NEO Earth Close Approaches |publisher=NASA/JPL CNEOS |access-date=27 February 2025 }}

For reference, the radius of Earth is approximately {{convert|0.0000426|AU|km mi|abbr=on}} or 0.0166 lunar distances.
Geosynchronous satellites have an orbit with semi-major axis length of {{convert|0.000282|AU|km mi|abbr=on}} or 0.110 lunar distances. In 2017, four known asteroids have traveled nearer than this: 2017 GM, 2017 UJ2, 2017 EA, and 2017 WE30. Unconfirmed asteroids YU95BEF, P10ELNY and A104Vqx probably have traveled nearer, but knowledge of their orbits is too poor to be sure.

The CNEOS database of close approaches lists some close approaches a full orbit or more before the discovery of the object, derived by orbit calculation. The list below only includes close approaches that are evidenced by observations, thus the pre-discovery close approaches are only included if the object was found by precovery.

This list and relevant databases do not consider impacts as close approaches, thus this list does not include any of the 29 objects that collided with Earth's atmosphere in 2017, none of which were discovered in advance, but were observed visually or recorded by sensors designed to detect detonation of nuclear devices.[https://cneos.jpl.nasa.gov/fireballs/ NASA.gov]

{{legend0|#ff9999|border=1px solid #ff9999|Rows highlighted red indicate objects which were not discovered until after closest approach}}

{{legend0|#ffff99|border=1px solid #ffff99|Rows highlighted yellow indicate objects discovered less than 24 hours before closest approach}}

{{legend0|#99ff99|border=1px solid #99ff99|Rows highlighted green indicate objects discovered more than one week before closest approach}}

{{legend0|#99ffff|border=1px solid #99ffff|Rows highlighted turquoise indicate objects discovered more than 7 weeks before closest approach}}

{{legend0|#bbccff|border=1px solid #bbccff|Rows highlighted blue indicate objects discovered more than one year before closest approach
(i.e. objects successfully cataloged on a previous orbit, rather than being detected during final approach)}}

= Warning times by size =

This sub-section visualises the warning times of the close approaches listed in the table of confirmed close approaches, depending on the size of the asteroid. The sizes of the charts show the relative sizes of the asteroids to scale. For comparison, the approximate size of a person is also shown. This is based the absolute magnitude of each asteroid, an approximate measure of size based on brightness.

Timeline of close approaches less than one lunar distance from the Moon in 2017

The number of asteroids listed here are significantly less than those of asteroids that approach Earth for several reasons. Asteroids that approach Earth not only move faster, but are brighter and are easier to detect with modern surveys because:

  • Asteroids that come closer to Earth are a higher priority to confirm, and only confirmed asteroids are listed with a lunocentric approach distance.
  • Those that closely approach the Moon are frequently lost in its glare, making them harder to confirm. They are similarly hard to discover during the new moon, when the Moon is too close to the Sun to detect asteroids while they are near the Moon.

These factors severely limit the amount of Moon-approaching asteroids, to a level many times lower than the asteroids detected passing as close to Earth.

Virtual impactors

List of asteroids with a Palermo Technical Impact Hazard Scale greater than −6 that are listed on the Sentry Risk Table because they have short observation arcs with poorly constrained orbits and have a chance of impacting Earth in 2017. Given a short observation arc, many different orbits fit the observed data. {{mp|2010 XB|73}} could have approached Earth around May 2017 or could have been 9 AU from Earth on the way to a close approach with Saturn in 2018. A Palermo rating of −4 indicates an event that is 10,000 times less likely than the background hazard level of Earth impacts, which is defined as the average risk posed by objects of the same size or larger over the years until the date of the potential impact.
